WILLIAM DORNAN, DE LOS ANGELES, CALIFORNIA, ASSIGNOR 0F ONE-HALF TO HAZARD & MILLER, 0]? LOS ANGELES, CALIFORNIA, A FIRM COMPOSED OF HENRY T. HAZARD AND HERMAN MILLER.

ANVIL.

To all whom it may concern:

bodying the principles of my invention and l 1 showing one operation.

The anvil body 1 has a flat upper face 2 and flat side faces 3 and 4 at right angles to the upper face 2. Channels 5 and 6 are formed in the side faces 3 ands, said channels being inclined downwardly from the rear end 7 toward the horn 8.

The clamping plate 9 has a flat lower face 10 to fit'the flat upper face 2. Arms 11, 12, 13 and 14 extend outwardly and downwardly from the side edges of the clamping plate 9 and fit loosely against the side faces 3 and 4. Lugs 15 and 16 extend inwardly from the lower ends of the arms and 14 and fit in the channel 6. Corresponding lugs extend inwardly from the lower ends of the arms 11 and 12 and fit in the channel 5.

The arms 11 and 13 are enough shorter than the arms 12 and 14, so that when the lugs 15 and 16 are in the channel the clamping plate 9 is parallel with the face 2 and the plate 9 moves toward and away from the face 2 as it is moved forwardly or backwardly relative to the anvil body 1.

The clamping plate9 may be readily removed when its use is not desired by running the lugs 15 and 16 out of the rear ends of the channels 5 and 6.

In the practical operation the clamping plate 9 is moved backwardly toward the end 7 and this operation raises the clamping plate 9 from the face 2, and due to the inclination of the channels 5 and 6 the clamping plate will stand wherever it is placed. When a bar 17 to be worked is placed upon the face 2 the clamping plate 9 is moved forwardly toward the horn 8 and this opera- Speciflcation of Letters Patent.

tion moves the clamping plate 9 downwardly to grip the bar 17 against the face 2. A blow of a hammer against the rear side of the clampin plate will drive the clamping plate tight then the bar 17 may be bent upwardly or downwardly or treated in the desired manner. When this work is finished a blow against the forward edge of the clamping plate will loosen the plate and the bar may be removed.

Various changes may be made without departing from the spirit of my invention as claimed. 1

I claim:

1. An anvil comprising an anvil body having a fiat upper face and fiat side faces, there being inclined mating channels in the side faces, a clamping plate having a flat lower face, arms extending from the clamping plate loosely against the side faces, and ln s extending from the arms into the chanhe s; so that the clamping plate will be raised or lowered as it is moved forwardly or backwardly.

2. The combination with an anvil having inclined guideways on its side faces, of a work clampin plate adapted to be positioned on top of the anvil and having parts that are adapted to occupy and traverse said inclined guideways.

3. An anvil comprising an anvil body having mating channels in opposite sides, a clamping plate having connecting means received in said Channels for clamping the clamping plate to the anvil body so as to hold work between the anvil body and the clamping plate.

4. The combination with an anvil, of a work holding plate adapted to be positioned above the working face of the anvil, and

connections between said work holding plate and said anvil whereby said plate moves into clamping engagement with the work positioned on the anvil when said plate is moved lengthwise relative to the anvil.

In testimony whereof I have signed my name to this specification.

WILLIAM DORNAN.
